High Mouse lag/latency on DEX

Discussion

I bought a tab S7+ with the keyboard cover. When using the mousepad, there is noticeable input lag for the mouse cursor. Feels almost like you are on a remote desktop.

For me showstopper for gaming or work on a DEX device.

They can bring down the pen latency to almost 0.... Why not for the mouse ?

Weird...

I've got the Samsung Galaxy Tab S6 and the Book Cover Keyboard and I don't notice any input lag from the touch pad.

I do know over the last year or so both the Tab S6 and the keyboard both had firmware updates. Perhaps the same needs to be done?

you shouldn't get lag when on the device itself...

I get the lag too both with a Bluetooth mouse and the touchpad.

It also applies when using a usb hub with an tethered mouse. Don't get me wrong, it is not like 1s delay. More like 300ms perceived... I don't understand why there is any lag at all, since it is a usb device.
